Mixing Rules
Do not mix the Cisco UCS 9300-8e HBA in the same server as the Cisco UCS 12G SAS Modular HBA.
Cisco UCS 9300-8e Bad Drive and Predictive Failure Behavior
The bad drive and predictive failure behavior for the Cisco UCS SAS 9300-e HBA cards is different than
that for LSI MegaRAID cards. The list below compares behavior for these HBA cards and LSI
MegaRAID cards.

Bad/invalid/0MB drive handling:
MegaRAID: The bad drive is marked BAD in the GUI/CLI interfaces and the fault LED on the
–
drive is solid amber.
HBA: The bad drive is not shown in the GUI/CLI and there is no LED indication.
–
Drive predictive failure:
MegaRAID: If the drive is part of a RAID volume with a spare, the software performs an
–
auto-copy backup and then marks the drive failed/BAD with the fault LED on the drive solid
amber.
HBA: There is no error handling and there is no LED indication. The operating system must
–
handle the fault.
